[LU-11224] T10PI assume several kernel features are enabled.

• Type: Bug
• Resolution: Fixed
• Priority: Critical
• Fix Version/s: Lustre 2.12.0
• Affects Version/s: Lustre 2.12.0
• Environment: Power8 running 4.14 kernel. Can be any kernel with options assumed to be turned on.
• Severity: 3
• Assignee: Li Xi
• Reporter: James A Simmons

Description

While porting to Power8 I ran into the following:

obdclass: Unknown symbol ip_compute_csum (err 0)

This is due to the new lustre T10Pi code assuming this is available. The same problem exist due to it assuming CONFIG_BLK_DEV_INTEGRITY is set.

• is related to: LU-11200 Centos 8 arm64 server support
• is related to: LU-11096 Lustre doesn't build if kernel has no blk integrity
